BEFORE INSTALLING
Please read the System Sensor Smoke Detector Application Guide, which provides detailed information on sensor spacing, placement, zoning, wiring, and
special applications. Copies of this manual are available from System Sensor.
NFPA 72 and NEMA guidelines should be observed.
NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: The detector used with this base must be tested and maintained
regularly following NFPA 72 requirements. The detector should be cleaned at
least once a year.
GENERAL DESCRIPTION
The B200SR sounder base is used with System Sensor 200-Series sensor heads
or equivalent. For a list of compatible sensors, refer to the System Sensor website at www.systemsensor.com. Refer to the appropriate manual for more information on sensors.
The B200SR sounder base was designed specifically to meet the needs of
dwelling unit applications. It offers maximum flexibility in configuration and
operation to meet or exceed the requirements of UL268 and UL464.
The sounder base is capable of producing either the distinctive three-pulse
temporal pattern (ANSI Temporal 3) fire alarm signal now required by NFPA
72 for commercial and residential applications or a continuous tone by simply
removing the included jumper from the device. Additionally, the B200SR is
designed to be compatible with existing installations of B501-Series sounder
bases.
The sounder base is intended for use with intelligent systems. The sounder
base requires an external 24 VDC power supply. The connections for the
external power supply and the communication loop are isolated to prevent
electrical interaction between them. Refer to the panel manual for maximum
allowable number of units per loop.
NOTE: For NFPA72 Installations, the Temporal 3 tone should be used for public
mode evacuation.
NOTE: When not used as a supplementary evacuation system, the external 24
VDC supply shall be treated as a component of the main power supply system
and shall fall under the requirements of the main power supply system per
NFPA 72.
WIRING GUIDELINES
All wiring must be installed in compliance with the National Electrical Code
and the local codes having jurisdiction and must not be of such length or wire
size which would cause the base to operate outside of its published specifications. The conductors used to connect smoke sensors to control panels and
accessory devices should be color coded to reduce the likelihood of wiring
errors. Improper connections can prevent a system from responding properly
in the event of a fire.
Wire sizes up to 12 AWG (2.5 mm2) may be used with the base. The sounder
base will be shipped with the screw terminals set for 14 AWG wiring. If 12
AWG wire is to be used, back out the screws to allow the wire to fit beneath
the clamping plates. For best system performance, the power (+ and -) wires
and the communication circuit wires should be twisted air or shielded cable
installed in a separate grounded conduit to protect the communication loop
from electrical interference.
Make wire connections by stripping about 3/8” of insulation from the end of
the wire. Then, slide the bare end of the wire under the appropriate clamping
plate (See Figure 1), and tighten the clamping plate screw. Do NOT loop the
wire under the clamping plate (See Figure 2) The wiring diagram for a typical
2-wire intelligent system is shown in Figure 4.
CAUTION
For system monitoring - for terminals 4 and 5, do not use looped wire under terminals. Break wire run as shown in Figure 2 to provide monitoring of connections.

TESTING AND MAINTENANCE
Sensors and bases must be tested after installation and as an integral part of a
periodic maintenance program. Test the B200SR as follows:
NOTE: Before testing, notify the proper authorities that the smoke sensor
system is undergoing maintenance and, therefore, will be temporarily out of
service. Disable the system undergoing maintenance to prevent unwanted
alarms.
1. If configured as in Figure 4 and 5, reverse the polarity of the external 24VDC
supply. If configured as in Figure 5, turn on the Intelligent Relay Module.
All B200SR bases on the loop should sound.
2. Latch the sensor LED on from the control panel. That individual sensor’s
B200SR should sound.
When performing maintenance on connected smoke sensors, carefully note
the location and address of each removed sensor.

MOUNTING
Mount the B200SR mounting plate directly to an electrical box. The plate will
mount directly to 4” square, 4” octagon, single gang and double gang junction boxes.
1. Connect field wiring to terminals, as shown in Figure 1 and 2.
2. Attach the mounting plate to the junction box as shown in Figure 3.
3. To mount the sounder base, hook the tab on the sounder base to the groove
on the mounting plate.
4. Then, swing the sounder base into position to engage the pins on the
product with the terminals on the mounting plate.
5. Secure the sounder base by tightening the mounting screws.
6. Install a compatible smoke sensor as described in the installation manual
for the sensor.
